INVALID-CHAIR.

Specification of Letters Patent.

Application filed March 16, 1909.

Patented J une 14, 1910. Serial No. 483,740.

To all whom it may concern:

Be it known that I, CHARLES FRANCIS IVALKER, a citizen of the UnitedStates, residing at Stockton, in the county of San Joaquin, State ofCalifornia, have invented certain new and useful Improvements inInvalid-Chairs; and,I do declare the followin to be a full, clear, andexact description or the same, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the characters of reference markedthereon, which form a part of this application.

This invention relates to improvements in household or hospitalfurniture and particularly to invalid chairs, the object of theinvention being to produce an invalid chair which in addition to itsfunction as an in valid chair can also be used as a rocking chair, thusgiving the invalid a more comfortable chair and permit a rocking motionwhich will overcome the fatigue and ache oc casioned by sitting in astraight and rigid chair.

A further object of the invention is to produce a simple and inexpensiveand yet effective structure for the purposes as set forth.

These objects I accomplish by means of a platform member mounted onwheels, a chair member having rockers mounted on said platform andsprings interposed between said platform and said chair. I also employsuch other and further structure and relative arrangement of parts aswill more fully appear by a perusal of the following specification andclaim.

In the drawings similar characters of reference indicate correspondingparts in the several views.

Figure l is a perspective view of the complete chair. Fig. 2 is asectional view of the platform and bottom of the chair, showing thesprings interposed therebetween.

Referring now more particularly to the characters of reference on thedrawings 1 designates a platform supported by wheels 2 and having afront foot rest 3.

4t is a chair member provided with side rockers 5, mounted on theplatform 1.

Interposed between the platform 1 and the bottom of the chair 4 on eachside are two springs 6 spaced apart and bearing on and secured to plates7 and 8 secured to the platform 1 and the bottom of the chair trespectively.

In practice the rockers 5 permit a rocking motion of the chair 4e on theplatform 1. The springs G maintain the equilibrium of the chair and atthe same. time gIX Q the same an easy, comfortable motion. The plates 7and 8 form the necessary bearing and securing surfaces for the saidsprings.

From the foregoing description it can be readily seen that I haveproduced a chair which, while having all the necessary functions of aninvalid chair, can still be used as an easy, comfortable rocking chairgiving the invalid an opportunity to assume comfortable changes ofposition.

IVhile this specification sets forth in detail the present and preferredconstruction of the device still in practice such deviations from suchdetail may be resorted to as do not form a departure from the spirit ofthe invention.

Having thus described my invention what I claim as new and useful anddesire to secure by Letters Patent is An invalid chair comprising ahorizontally alined platform mounted rigidly on large front wheels,small wheels turnably disposed beneath said platform at the rearthereof, a chair having rockers bearing on said platform, plates on saidplatform and on said chair, springs interposed between said plates, saidrockers bearing the weight of the chair.

In testimony whereof I affix my signature in presence of two witnesses.
